TWMXRS by SPY is the premier amateur racing series for year round action.  Throughout the season there are four individual series of five races each.  The TERRA FIRMA SERIES host the annual summer rounds which kicks off July 9th in Riverside, CA at Milestone MX and you can pre register now if you CLICK HERE.

Milestone MX just informed us that they will be doing major track changes over at the ranch to both the Main and Vet tracks the week before our kick off race July 9th.  The dual track format benefits from using both these tracks and we can’t wait to see what they design.

Yamaha has been a valued parter of the TWMXRS since it’s inception.  Yamaha also has a unique offering within their So Cal Owner Benefits Program giving new Yamaha owners a free membership to TWMXRS and exclusive free practice at some of the tracks visited by TWMXRS as well.  Anyone who has raced with us in 2017 has seen that beautiful 2017 YZ250f proudly displayed next to registration.  For every class entered racers have been given a chance to win this bike and we are excited to announce we are giving it away at Round #1 of the Terra Firma Series at Milestone MX!  That’s right one lucky member will take home this class leading machine which also won the 2017 250 Shootout by Transworld Motocross Magazine and Bike of the Year.  Must be present to win so make sure you don’t miss this even July 9th!

Bell helmets have also been a proud supporter of the TWMXRS and in years past they hosted demo programs and offered deep discounts for top finishing racers.  During the West Coast Open Bell decided to take the group of overall champions and randomly give away one brand new Bell Moto 9 FLEX!  The randomly drawn winner of that helmet is Kaiden Lyle of Menifee, CA.  Kaiden races in the 65cc Beginner Class and competed in all five rounds visiting Milestone MX, Glen Helen Raceway, LACR and Cahuilla Creek.  His worst overall was an 8th place and his best finish was taking the win at LACR and he won the overall by just four points.  Congratulations Kaiden from Bell and TWMXRS!

The Terra Firma Series is also adding a new track to the TWMXRS by SPY that we haven’t visited in a very long time!  For our San Diego County riders we are excited to be visiting Pala Raceway for Round #2 on July 23rd.  Our fearless race director Craig Davis will be working with the Pala Raceway staff to adapt the layout to our unique two track format and over 60 classes of riders skill levels.  Racing will take place on the Main and Amateur tracks at the world famous facility.

We are very excited to kick off another great series of racing with TWMXRS by SPY!  Don’t miss a single stop!
